Overall our team is very happy with Hubspot. Unfortunately it is the small things which pisses the off, to be honest.
Being Able to create or copy paste a table into an email should be a piece of cake. As tables are a very common way to communicate structured information in sales or CS this should be possible.
I think it should also be possible to copy paste files, e.g. emails or PDFs, into emails…instead of uploading them manually which is not handy at ALL. So my message here is- your editing features for email need som love
